both attachments are to the same system, or to a tightly-coupled system, and the attachments are of the
same type channel (example, both are ESCON or both are parallel channel), then switching between the
two attachments can be performed dynamically by the host system. If the attachments or host differ, or the
hosts are not tightly-coupled, then the switch must be performed manually by the operator. The printer
must be disabled from the current system and attachment before it can be enabled to the other
attachment.
System/370 Parallel Channel
System/370 parallel channel attachment is supported on OS/390, PSF/MVS, PSF/VM, and PSF/VSE
printing environments.
vFor S/370 parallel channel attachment, a control unit position on a S/370 parallel block multiplexer
channel is required on an IBM 3090
™
or ES/9000
™
processor.
vThe following processors are also supported for S/370 parallel channel attachments: S/390 Parallel
Enterprise Server, and the S/390 Multiprise 2000 servers.
vAttachment is also supported via the 9034 ESCON Converter Model 1.
ESCON Channel
ESCON channel is supported on OS/390, PSF/MVS, PSF/VM, and PSF/VSE printing environments.
vThe IBM Infoprint 3000-ES1 and 3000-ED1/ED2 may be attached natively to IBM ESCON channel
(3090-J, 9021, 9121, 9221, 9672, 2003).
vAttachment is also supported via the 9032/9033 ESCON Directors and 9036 ESCON Remote Channel
Model 1 and Model 2.
The ESCON attachment may be shared between different ESCON systems or different ESCON multiple
image facility (EMIF) images, if ALLhost systems connected to the printer are using the OS/390 (V1R3.0
or higher) operating system and ALLof the PSF/MVS applications in those systems have the APAR
OW29992 installed. Such OS/390 systems can be guests of VM/ESA.
When these conditions are met for ESCON then the multihost flag can be set to “TRUE”in the printer.
This will automatically invoke the protocol allowing the printer to print only one host (or OS/390 guest of
VM) at a time. When the first host is printing the second host will receive an “assigned elsewhere”
message until the first host is finished printing and releases the printer.
Token-Ring (TCP/IP) Attachment
Token-Ring(TCP/IP) attachment is supported on PS/400, PSF for AIX, and Infoprint Manager for AIX
printing environments along with selected RS/6000 and AS/400 models. The 3000-ES1 and
3000-ED1/ED2 are connected to the host Token-Ringthrough the IBM Token-Ring cabling via the Token
Ring High-performance adapter, which is contained in theAFCCU. The control unit can be attached to
either a 16 Mbit/sec or a 4 Mbit/sec Token-RingLAN. The TCP/IP Token-Ring Attachment will attach to the
following devices:
v8228 TokenRing Multistation Access Unit attached to an AS/400 or RS/6000 processor
v8230 TokenRing Network Controller Access attached to an AS/400 or RS/6000 processor
v8228 TokenRing Multistation Access Unit attached to a 3172, 3174, 3745, 3725, or 3720 attached to a
3090, ES/9000, or 308X processor
v8230 TokenRing Multistation Access Unit attached to a 3172, 3174, 3745, 3725, or 3720 attached to a
3090, ES/9000, or 308X processor
The printer may be located at a maximum distance of 100 meters (328 ft) from the 8228 Multistation
Access Unit or 8230Controlled Access Unit.
The distance between the 8228 Multistation Access Units can be increased with either the 8220 or 8219
Optical Fiber Repeater.
vInstallation Instructions are provided with the feature.
